value is stored in the variable.

+ If the regular expression does not match, then the reference variable
will be set to the default value.
+ This is particularly useful for debugging tests. If no default is
provided, then it is difficult to tell
+ whether the regular expression did not match, or the RE element was
not processed or maybe the wrong variable
+ is being used.
+ <p>
+ However, if you have several test elements that set the same variable,
+ you may wish to leave the variable unchanged if the expression does
not match.
+ In this case, remove the default value once debugging is complete.
